Question

When 6 is subtracted from the length and 3 is added to the breadth of the rectangle, the perimeter becomes 24. Write the mathematical form of the statement using variables x and y. (length is x and breadth is y)​

Answer 1

x+y=24

3+y=24

y=24\3

y=8+3

y=11

Answer 2

Answer:

let length be x and breadth be y.

so, new length= x-6 and new breadth=y+3

so, p= 2(l+b)=> 2[(x-6)+(y+3)]=24

=>x-6+y+3=24/2=12

=>x+y=12+6-3=18-3=15

=>x+y=15.
